Revelations of Divine Love was written by Julian of Norwich (1343 – after 1416), an English anchoress and mystic. Julian's dates can be surmised from various sources: Julian herself wrote that she experienced her revelations when she was thirty and a half years old in May 1373 (in chapters 2 and 3 of her Revelations), and the author of the preface to the so-called Short Text version of Julian's writings stated she was still alive in 1413. The celebrated mystic Margery Kempe wrote about her visit to Julian, which probably occurred in 1413. She is also mentioned by name in Isabel Ufford's will, which is dated 1416. The English antiquarian Francis Blomefield incorrectly wrote in the second volume of his History of the County of Norfolk that Julian was still alive in 1442.

Throughout her life Julian lived in the city of Norwich, an important commercial and religious centre in England during the Middle Ages. The Black Death of 1348–50, the Peasants' Revolt of 1381, and the suppression of the Lollards, all occurred during her lifetime.

In 1373, seriously ill and convinced she was close to death, the 30-year-old Julian received a series of visions, or 'shewings', of the Passion of Christ. All the revelations but one appeared to her over a period of several hours during one night; the last occurred a day later. After recovering from her illness, Julian lived the rest of her life as an anchoress, in a cell attached to St Julian's Church.

Details of her life remain unknown, but she is known with certainty to have existed, as she was the recipient of a number of wills, and she is mentioned in an account by Kempe, who met her at her cell in Norwich. It is not known for certain whether the name Julian was adopted once she became a recluse: the authors Liz McAvoy and Barry Windeatt have both commented on the lack of historical evidence that the true names of anchoresses were ever changed to match the patron saint of the church they belonged to, pointing out that Julian was a common girl's name during the Middle Ages, and McAvoy notes that Julian is the old form of the modern name Gillian.

Julian referred to herself in her writings as "a simple creature unlettered", a phrase perhaps used to avoid antagonising her readers, especially in the ecclesiastical hierarchy. The term unlettered in the Middle Ages might have meant that she was herself illiterate, or that she did not receive a formal education, rarely available to laywomen. The city contained many convents whose orders recognized the importance of education. Many had boarding schools for girls, where they were taught to read and write. Scholars are not sure whether Julian attended such a school. It is possible that Julian had an educated brother and became literate through him.

Revelations of Divine Love is unique, as no other work written by an English anchoress seems to have survived. It is the first book in English known to have been written by a woman. In the 14th century, women in England were generally barred from high-status clerical positions or other authoritative roles such as teaching, and their knowledge of Latin, the lingua franca of the day, would have been limited. It is more likely that they read and wrote in Middle English, their vernacular language, as Julian did. Her life was contemporaneous with four other English mystics—Walter Hilton, Richard Rolle, Margery Kempe, and the unknown author of the work known as The Cloude of Unknowyng—all of whom wrote in the vernacular. The historian Janina Ramirez has suggested that their use of Middle English was a sensible choice, considering the inexplicable nature of what they were attempting to describe, as they could "couch their theological ruminations more as personal encounters with the divine". Julian's writings were not mentioned at all in any bequests, in which personal libraries of lay or monastic books were distributed within wills, as often happened for male authors at that time.

Some Middle English spiritual texts were written for a specific readership, such as The Cloude of Unknowyng, which was intended by the author to be read by a young hermit, but Julian wrote as if for a general readership. There is no evidence that her writings influenced other medieval authors, or were read by more than a very few people, until 1670, when her book was first published by Serenus de Cressy under the title XVI Revelations of Divine Love, Shewed to a Devout Servant of Our Lord, called Mother Juliana, an Anchorete of Norwich: Who lived in the Dayes of King Edward the Third. Since then the book been published under a variety of different titles, and has become celebrated by Roman Catholics and Anglicans because of the clarity and depth of Julian's visions of God. Since the 1960s, a number of new editions and renderings of her book into modern English have appeared, as well as publications about her.
